Question: why do we have headaches?

Bernice Ridley answered on 8 Mar 2023:

Pain is a response to nerves firing off electrical signals due to something happening in the body, be it an injury, pressure, hot or cold. Headaches are interesting as sometimes we don’t know why we have them. Obviously, if you have banged your head it will hurt, or if you have strained the muscles in your neck that support your head. If you haven’t drunk enough water then you can get a headache due to dehydration in the tissues. If you get a headache when you are stressed it could be due to you clenching the muscles in your neck or shoulders, and massaging your shoulders can help to relieve it. There are many more types of headaches and I am not a doctor so I couldn’t explain why they happen, I just know they are annoying!
